Portrait — Side-by-Side Results
Prompt
"Portrait photo of a 20s woman with shoulder-length wavy dark hair in a cozy oversized hoodie and simple gold hoops, holding her phone slightly above eye level and glancing toward the camera mid-sip of an iced latte. Candid café corner setting with a window beside her, soft natural daylight on her face, shallow depth of field with warm bokeh from background lights, authentic “Instagram story” vibe. Shot like an 85mm portrait with realistic skin texture and a relaxed, approachable expression."

Flux 2 Strengths
- Higher-detail portrait output up to 4MP, helping preserve hair strands, skin texture, and subtle lighting gradients in close-ups
- Versatile image-to-image editing for refining headshots (pose tweaks, wardrobe adjustments, background cleanup) without restarting from scratch
- LoRA fine-tuning support for consistent portrait styling (brand look, creator identity aesthetics, recurring lighting setups)
- Style transfer and face-swap support for controlled portrait variations and campaign-ready consistency
- Two pricing tiers (Standard and Klein 9B) to balance portrait quality vs. credit spend depending on the shoot concept
Z-Image Turbo Strengths
- Ultra-fast portrait generation, ideal for rapid headshot exploration and high-volume iteration (expressions, framing, outfits)
- Cost-effective at 8 credits per image, making it easier to run broad casting-style grids and concept tests
- LoRA support for applying a consistent portrait style quickly across many images
- Solid baseline text-to-image and image-to-image for straightforward headshots and simple environmental portrait setups
- Great fit for workflows where speed and quantity matter more than maximum facial micro-detail
Verdict
If your portrait work prioritizes high-fidelity close-ups, nuanced skin/hair detail, and a more complete editing pipeline for polishing final headshots, Flux 2 is typically the better fit—especially when you need controlled revisions and consistent campaign-ready outputs.
If you’re producing lots of portrait options quickly (auditions, moodboards, A/B tests, batch variations) and want to minimize credit spend while keeping quality “standard-good,” Z-Image Turbo is the practical choice. Many teams use Z-Image Turbo for fast iteration, then switch to Flux 2 for the final selects and refinements.
